PROCESS OF APPLYING COLORING LIQUID TO PAPER Application tiled August 8, 1919. Serial No. 316,284.

To all whom it may concern:

Be it known that we, LESTER P. WINCHEN- BAUGH and LAWRENCE GnN'rILn, citizens of the United States, residing, respectively, at

Hyde Park and Melrose, in the counties of Suffolk and Middlesex and State of Massachusetts, have invented certain new and useful Improvements in the Processes of Applying Coloring Liquid to Paper; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a process of ap plying dye, stain or other coloring liquid to paper or similar material.

The primary object of the invention is to devise a process for use in applying coloring liquid to paper by which novel designs and artistic effects may be produced. With the above object in view the invention consists in certain novel features here inafter described and particularly pointed out in the claims.

In the drawings Figure 1 is a View in side elevation of an apparatus which may be employed in carrying out certain steps in the present process illustrating the manner in which the coloring liquid is applied to the paper; and Fig. 2 1s an underside plan view of a portion of this apparatus.

In the present process a coloring liquid is employed which, in practice, has been made by dissolving a dye in a liquid solvent. The dye substances which are employed should be such that they are completely soluble in the liquid solvent, leaving no sediment. Preferably coal tar or aniline dyes are used, such dyes having in addition to their ready solubility the property of transparency which enables almost countless variations in color and designs to be produced by superposing the colors. It has been found to be particularly advantageous to employ as solvents for the dye alcohol, gasoline or similar organic solvents since such solvents produce a rapid drying solution and cause the color ing liquid to penetrate the paper to a considerable degree, thereby causing the same to spread from the point of application and increasing the artistic efl'ect of the design. After the dye is completely dissolved in the liquid solvent the coloring liquid is preferably introduced into a suitable container havlng one or more color delivery openings therein. The coloring liquid is applied to the paper by placing the paper in contact with the container at the point where the delivery openings are formed therein, and moving relatively the container and the paper to distribute the coloring liquid along the paper. The coloring liquid will thus be delivered to the paper in one or more streams as the paper is moved past the container and will be applied to the paper in a design depending on the size and arrangement of the color delivery openings in the container.

The design made by applying the coloring llqllld to the paper in this manner may be varied by varying the form and size of the color delivery openings in the container. Thus the paper may be given a solid colormg by forming the container with a slit extending substantially the whole width of the paper, or the coloring liquid may be applied to the paper in stripes by forming the container with a series of relatively small openings, the width of the stripes varying with the width of the openings. The stripes may be made in wave form by imparting .a relative lateral vibratory motion to the paper and the container as the paper is carried past the container.

The amount of the coloring liquid which is deposited upon the paper may be varied by varying the rapidity of the relative movement of the paper and the container. The greater the speed with which the paper is moved past the container the less will be the amount of the coloring liquid deposited on the paper.

When liquid solvents having the quality of rapid penetration such as those described above are employed the coloring liquid will penetrate the paper to a considerable degree, thus producing very artistic efiects. It has been found that the extent to which the coloring liquid penetrates the paper is reduced by mixing water with the solution.

Thus the penetration of the coloringliquid into the paper may be regulated by adding a predetermined quantity of water to the dye solution. Where it is desired that the paper shall have a surface coloring only a iii) cated at 4 to which the coloring cessively past the same.

'Two or more colors may be applied to the paper at the same time bypassing the paper past two containers containing coloring liq uids of different colors. The color delivery openings in the two containers may be so arranged that the second color is applied to the paper at certain points over the first color, or the colors may be made to overlap at certain points. Wheretransparent dyes are employed very beautiful and artistic color eiiects may thus be produced.

When the above process is followed the coloring liquid is thus applied upon localized areas of the paper and is applied in quantity sufficient to cause the same to penetrate the paper to a very marked degree and to spread from the point of application, giving a design without hard sharp edges and producing very artistic eflects. Tn certain instances, the" coloring liquid passes completely through the paper so that the side of the paper opposite that to which the coloring liquid is applied may be used as the display side thereof.

Tn the drawings is illustrated one form of apparatus which may be employed in carrying out certain steps in the present process. This apparatus is embodied in the machine illustrated and described in the copending application of Lawrence Gentile, one of the present applicants, Serial No. 251,384, filed Aug. 26, 1918.

This apparatus comprises a container 2 for the coloring liquid consisting of a pipe provided with color delivery openings as indiliquid is supplied in any suitable manner. To guide the paper and hold the same in proper contact with the container, guide bars 6 arranged on opposite sides of the container are provided. The paper is passed alternately over the guide bars and under the container pipe so that the pipe forms a bight or loop in the paper and the paper passes partially about the lower portion or face of the pipe where the delivery openings are formed. Where it is desired to apply two colors to the paper at the same time two containers for coloring liquids of different colors may be arranged so that the paper is carried suc- In this case itwill be found desirable to make some provision for drying the paper after the first and before the second color is applied. By suitably arranging the color delivery openings in the two containers various designs and arrangements of the colors may be produced. The second color may be applied in overlapping or' superposed relation to color at certain points so as to form a combination color or color mixture.

Having explained the nature and object of the invention and having specifically described the manner in which it may be applied, what is claimed is:
